Could it be related with this?

In fact in this configure.ac I found the static library is searched explicitly:
http://support.red-fone.com/fonulator/fonulator-1.5.1/configure.ac

```
# Optional shared linking with libfb
LIBFB=
 AS_IF([test "x$with_shared_libfb" = xyes],
	AC_CHECK_LIB([fb], [libfb_init],
		     [AC_SUBST([LIBFB], ["-lfb"])
		     AC_DEFINE([HAVE_LIBFB], [1], [Define to 1 if you have libfb])
		     ],
		     AC_MSG_FAILURE([test for libfb failed (required)])),
		     # otherwise, we need to link static libfb and also link in libnet and libpcap
	# Check for static libfb
	AC_CHECK_FILE(/usr/local/lib/libfb.a,
	      [
	      AC_SUBST([LIBFB], ["/usr/local/lib/libfb.a"])
	      AC_DEFINE(HAVE_STATIC_LIBFB, 1, [Define to 1 if you have the static version of libfb in the right place.])
	      ],
	      [AC_MSG_ERROR([Couldn't find static libfb libraries])])
    )
```

I've not check it, but if the info in the first link is correct I guess that installing the libs in a "standard" path will fix this Autoconf problem.


Anyway. What I did was very simple:

``` $ diff -Naur configure.ac.old configure.ac
